Answer:
Magnetivity and melting point.
Explanation:
Aluminum, steel and tin cans can be separated by two step process of magnetisation and melting point, because the three cans have different magnetic properties.
Steel attract to magnet easily because of it's has magnetic properties and these separate steel from aluminum.
Neither steel and aluminum melted at 300°C but Tin melt at that temperature.
Answer:
1.7
Explanation:
Density = M/V
When you divide 4.52 by 2.6, you get 1.738461538, which can be simplified to 1.7.
The answer will be Magnesium. It is a two positive ion and it can charge electrons and protons.
Answer:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Explanation:
Chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O
Balanced chemical equation:
Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O
The given reaction is double displacement reaction in which anion and cation of both reactant exchanged with each other. Calcium hydroxide react with sulfuric acid and form calcium sulfate and water.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AD +CB
